Title: Glock 40 vs 20?
Post by: will965 on March 31 2015 10:16:56 AM MDT
Gents,

been kinda waiting on the Glock 42 come out now and was thinking about going ahead and buying one and getting my name on the list at our local le dealer.but I was thinking what advantages would the 40 have over the 20? After all if we are planning on shooting lead reloads are we not going to have to put a replacement barrel in anyways? What advantages would the 40 have over the 20, maybe the mos system? But if one does not plan on putting hunting sights on it, is it worth it? I gotta gets me one soon, lol....

I run a lot of lead through my Glock with no issue.

IMHO the problems with Glocks and lead are that guys don't follow the rules:  Slug your bore and used cast bullets at least .001" over groove diameter.

My Glock 29 factory barrel slugged just a hare over .401".  That means commercial cast bullets sized .401", that are too hard and have poor lube, are definitely going to lead the barrel like crazy.

My own cast bullets unsized measure about .403", are from moderate hardness lead (BHN 12-13) and are lubed with a messy but effective medium soft lube run just fine in my G29.

All that said, the G40 strikes me as a hunting or target gun.  Set up for optics from the factory, too long and heavy for comfortable carry, even in a duty holster.  The extra slide mass will certainly help on nuclear loads though.

The 40 is going to have even less market than the 20, but it'd be interesting to see if the Gen4 G40 will or will not have the FTF issues the Gen4 G20 has.  I wonder, as crazy as it seems, if putting some weights on the Gen4 G20 slide would help FTF issues for those that have them.

As Sqbullet said, G40 for hunting, silhouette shooting, or maybe as a dedicated target gun.

G20 for carry / home defense / range gun.

I am sure it won't.  And if we had the MOS system on the Gen4 G20 you could make a mint selling platinum MOS covers that would add mass to the slide.

Glad i read this as I am try to read bout everything in this website about the g20....didn't know it had ftf issues....wow...stock? Kinda sucks as these were thReae two I was looking too next

Some of the Gen4's have FTF issues with the very, very hottest loads from Underwood.

No reason to shy away from the G20.  You will find plenty of very, very stout loads that run great

I run a 24 pound RSA in mine for the Underwood etc. and it runs great.

Others haven't been so lucky, but I think the problems exist with the earlier Gen 4 guns.

To try to ease your mind a little I have had zero reliability issues from my Gen 4 20.

Some Gen4 G20 have FTF issues not just with Underwood but with stout 10mm power ammo.  The issue is not so much the FTF but the fact that Glock's 'fix" is to play dumb on issue, returning a FTF as 'no problems found', unless pressed, then their "fix" is to give a Gen3.  Only one person so far that I know of has fixed their Gen4 G20 FTF issue, by using a higher pound recoil spring.  Others have tried that and it didn't work, so your mileage my vary on trying to fix a misbehaving Gen4 G20.

I for one hope there are a lot of G40's sold and we get some users reporting here with higher power ammo.  I'm interested myself in seeing if the heavier slide helps or not.  Time will tell...

Isn't the main difference in slides for Glocks in different calibers the weight of the slide? If acceleration is equal to Force/Mass, it would seem increasing the weight of the slide would slow it's speed in recoil. Occasionally I've thought of putting lead tape on a slide to see if it made any difference.....but, I'm lazy. ;)

OP, you shouldn't have any issues with either when it comes to functionality. As sqlbullet stated, follow his suggestions on shooting lead.

I think the main problem is that most people don't clean their guns - especially the bore. Many people think that a pistol doesn't need to be clean, or worse, they think that cleaning it will cause more problems than not cleaning it.

The rumors I've heard, and they are rumors, so take them what they are worth, the G40s should be shipping later this late spring, early summer.

The G40 is a cool idea, but I personally would have more use for a 20.  Then again down the road if I see one I may grab it.

I see it as glock 40 for hunting animals and glock 29 for people theres no reason to own a model20 now?

Seems like Glock is doing the right thing.

Long, medium, short.

I bought my 20SF and turned it into a long slide before I knew about the 40. It is what it is, and I still have the standard slide and barrel and mess of other barrels. I'm a happy camper.

Negative ghost rider!

The glock 20 is a fine piece of shootin' iron. IMHO is is Glock's best.  ;)

You won't regret a G20!

I carry a 20 frequently. What does that do to your point?

My point is sirs my glock 29 will do anything that my glock 20 will do. When i sumday soon buy a m40 my m20 will just be in the safe. Theres nothing wrong with a glock 20 ive killed 3 deer and 1coyote with one. Sum glock owners buy every size model glock they make. Me personally how i use 10mm the smallest and largest models r what i most use.

I see no reason for the Glock 29. The G20 is for home defense or open carry (trail gun), and the G40 is for hunting. If I need something to conceal, it will be my G20 9mm, XDS 9mm, Colt Officers 45ACP, or S&W 60 357.

I kind of feel different. I conceal my Glock 21 Gen 4 everyday even during hot weather under shorts and a t-shirt. If things get really hot I do change to the Glock 30 but I have no trouble concealing the 21. Besides. 16 rounds of 10 millimeter kind of gives me a warm and fuzzy feeling.

I will eventually get a 40, but my 20 isnt going anywhere.. it is my favorite pistol and only my 23 and ruger 22/45 come close. I really do not have a problem concealing the 20, i dont have any expensive holster so i usually end up using a desanits generic leather iwb and appendix or small of back carry with it.

I'm with these last few posts; the 20 and 29 fill their respective roles and the 40 will fill a role that the 20 and 29 sometimes can't. It's possible to turn either into an optic running long-slide, sure, but not without a bit of doing (and time, and money) on the owner's part and that usually entails quite a few aftermarket parts. Some people aren't comfortable doing that much work on their own guns, or don't have the time, or just simply don't want to, if for no other reason than their preference for keeping their guns "factory." There's as many reasons as their are owners. In my mind the 20 can do most of what the 40 does, as far as hunting and target shooting goes, but at the same time it's role is more specific so its applications are more limited. The same can be said of the 29 and the 29; each has their advantages for their respective owners and each does A job but sometimes it's better to have a better-optimized tool for a particular job, as anyone who uses tools professionally will attest to. In my opinion the 40 will never fully replace the 20, that's just out of the question, but it will certainly have a solid presence in the market area that it hopes to enter. I appreciate that Glock is expanding its offerings and is interested in trying new things and developing new products, even if they're slightly more esoteric sometimes. It's always nice to have options, especially if you're that guy out there that just loves Glocks but absolutely refuses to buy a bunch of aftermarket parts to build his own long-slide 10mm with an optic to go enjoy his first hog or whitetail hunt. For him the 40 is what he wants, for me the 20 is what I want and now we're both happy.

There is no doubt that Glock is going to sell a good number of G40's. They won't sell as many as they will of the new single stack 9mm Glock 43 (which will sell in droves), but the G40 is here to stay in my humble opinion.

To be honest, when the concept of the G40 first came out I wasn't all that interested. I figured two G20's was enough. But now I think I will be taking a serious look at the 40.

Great discussion!
