And wonder if....
A) the NY-1 trigger spring and 3.5 connectors used in the Glock 17 work in the 40.
B) is there a heavier recoil spring set made for the 40?
C) Will the hard case 220 (Buffalo Bore), 230 (Double Tap) grain factory loads function reliably?
D) and if you were going for simple and strudy adjustable open sights what would you suggest (mine still has the Glock plastic sights.. adjustable but I'd prefer steel.)
Thanks!!
First if all congrats on your G40. Mine is rapidly becoming my favorite 10mm, and favorite handgun.
The trigger in the G40 should be the 4.5 pound trigger. Mine isn't bad at all. I don't believe they are the same parts as the G17 but I could be wrong on that.
It's the same RSA as the G20. The weight of the slide dampens recoil.
My G20 ran both the Buffalo Bore 220 and the Double Tap 230 reliably. I haven't tried them in the G40, but I think they will be fine. The G40 reliably feeds the Underwood 220 grain powder coated hardcast load.
The Glock brand adjustable sights are decent. I don't have any recommendations on other adjustable brands.
Thanks.
"The weight of the slide dampens recoil." Yes is sure does!
Now I usually hike with a Ruger Security Six .357 4 inch revolver and handloads that give the 158gr SPs at 1200 fps. Kind of hurts my hand after 30-40 rounds practice. The Glock 40 does not at all!! Full 10mm loads are just easy to shoot. 3 inch groups at 25 yards with just Miltech 10mm ammo (I plan on trying SIG 180gr JHP 10mm as I understand it is much more accurate.)
I'll get a NY-1 trigger and 3.5 connector and try. I use that setup in my carry Glock 26 as I like bit heavier trigger with no stacking at the end of the pull.
I just may leave the sights as-is... I was even tempted to fork over $$ for a Bar-Sto barrel and hard chrome finish but $1000 Glocks are not my cup of tea! I got this one at a pawn shop for $546, tax included.
And if I go back to Alaska again... the Glock 40 will be carried. Yes I have .44 magnums but full house loads are very hard to practice with and I'm a firm believer in practice!
Thanks again.
I have the plastic sights and they aren't bad. I had the Glock brand night sights installed on my G20 due to the fact that I carry it in the woods at night.
The Glock barrels are extremely reliable. Good luck with whatever you choose to do...!
For aftermarket sights you might look at Dawson Precision...very nice but not very cheap. The adjustable black rear sight and red fiber optic front sight is what I chose, and I like it. I used to run nothing but night sights, but since I don't shoot at night anymore it seemed silly to keep paying for them.
My Glock 20 Gen-4 would NOT reliably cycle Underwood 220 grain bullets without a spring change. I went to a 20lb spring from Lone Wolf and everything runs well with that, including mild loads like S&B 180 grain factory ammo. Underwood said that their 220's were the most problem-prone round for cycling, but that most guns will cycle the 200 grain hardcast without a spring change. You just have to run a few boxes through and see for yourself.
Some people have had issues with the Glock barrel stabilizing 220 grain slugs. Again, you just have to try and see. Since I shoot virtually nothing but 200 and 220 grain hardcast loads, I put in a KKM barrel and don't have a lot of experience with the factory barrel.
Have fun!
I got a G40 and a second G20 a few weeks ago in trade. So far, I really like the G40 but I noticed it's a little nose heavy compared to my G20s. I think it should even out with some additional range time and an RMR when I can afford it.

Muskrat, is the 20lb spring a Gen 3 spring set up to work on a Gen 4? And is 20lb heavier or lighter than standard weight?
I wish someone would make a Gen 4 stainless steel recoil spring set that was about 2 lb heavier than stock.. but I sure don't see one made.
Thanks.

cdrepine, yes mine feels a bit 'muzzle heavy' but I sure do like the fact it does not recoil badly at all.
I think 15 rounds of 200 grainers in the grip balances out the weight some.
I think Glock hit ball out of the park with the model 40 MOS. I added a 7" KKM barrel to mine it was a great addition for velocity and accuracy as well as easier on brass.
Deaf Smith...the spring is like a Gen-3 spring in that it's not progressive, just a single spring on a single rod. It's heavier than the stock Gen-4 progressive spring. I'm not entirely positive that it's not a 22lb spring, now that I think about it.
I have a 24lb spring that I'm going to try...tired of my brass going 30 feet, and if I want to shoot powder puff loads I can just put the stock spring back in.

My g40 runs all above mentioned ammo with ease. I'm running an RMR and ameriglo suppressor height sights. Only thing I did was add alpha wolf barrel and ghost connector.
