1911 owners, we are doing it wrong!

For a 10mm I would guess 10,000-20,000.

I wonder if it would be less rounds than that with a steady diet of all premium Underwood loads.

That is based on full bore 10mm loads.  If you back off to 180 grain at 1200 fps, you should get somewhere between 38 super and 45 acp life out of the slide, since you are running at the same MAP chamber pressures as those rounds.

Would you limit what you said to quality firearms?

I wonder how that might vary between different frame/part manufacturing tecniques like:  cast, machined, forged, electro-chemical...  Not to mention how the difference between cro-moly and stainless steel might affect the outcome.  I don't know, just throwing some food for thought out there.

[sqlbullet]

Yes. That assumes forged or bar-stock machined slides.  STI comes to mind.

There are some changes that a really sharp engineer might make to the slide that would help some.  Minimizing stress focus points.

Yep, a sharp engineer would get rid of all those sharp inside corners! And make the slide a little thicker. I'm surprised nobody makes beefier 1911 slide? It wouldn't have to add much weight, and wouldn't take a rocket scientist to figure out.

The short frame rails of the 1911 are another concern for high energy loads like the 10mm though. The CZ design (ala Witness) is great in that respect, although it has other issues.

It has been a few (19) years since I really looked closely at a Glock slide, but this is the area I think it is really built for the 10mm.  The way the barrel locks into the slide coupled with a flat breech really go a long way to making it both stronger and more durable.

I believe a purpose built 1911 from the ground up toward handling all a 10mm can offer, at at least a semi-reasonable price point would probably generate alot more attention than most could imagine.  If it existed I would own it.

Maybe a Shock Buffer would do the trick?

The hammer spring in my 2012 RZ-10 seemed light for a 10mm.The sticky on a 1911 forum shows them to be 18.5 pounds,the same as their 45acp's.I detailed stripped my RZ-10 and put a wolf 21 pound spring in it.I polished the sear nose and hammer hooks with ceramic white and ruby stones and the trigger breaks at 4 pounds with no creep.It feels like 3 pounds.I use a wilson 22 lb FL guide rod system with shock buff.It runs flawless and is very accurate.I'm impressed with the quality inside and out.They only made 50 for 2012 and very glad I got one.I shoot mostly 180 LFN's over 6 grains WSF.Light recoil and shoots under 2 inch at 25 yards.

'10d' Nice gun. Thinking about getting a RZ10 myself.

[Intercooler]

10d where did you get yours? I got lucky and tried to pass on the deal... I was out the door for $1150 shipped.

I really love mine and now I see they are $1400 on up.

Im gonna chime in and opted to keep my Witness Match with 180's from Underwood and 200's with a 18 lb spring.I reserve more powerful loads for the Glock.I know the Match can handle more,but is it really prudent,no.That damn Glock jut rocks.That was my intention and it works.Of course the lite stuff is used for punching paper.The Glock and Witness are like "Jacob and Esau".

[Intercooler]

Now Now. You can't tell me you like the G20 as much as the Match.

[REDLINE]

That damn Glock jut rocks.

The G20 and G29 are awesome having the simplicity (even with numerous safety measures built in), durabilitly, round count capacity, and unerring reliability, all at the same time in a 10mm package.  I think Mr. Glock simply kept cosmetics to a minimum to show he wasn't greedy, giving other manufacturers a chance in the marketplace.  Still something to be said about a blacked out look except for the white in the sights.  Truely an engineering feat!  Personally, I wouldn't want it any other way.  Guess that's why I own them both.

I got mine from a place in KC.It is single digit serial #.One of the first.I had to pay retail.I wanted to make sure I got one.You got a very good deal for a 2012.Hang on to it.Probably the only way to get a better 1911 in 10mm is to get a Nighthawk or Wilson Combat and you'll wait a long time and pay twice as much.STI and Fusion make very good 10mm's also.The 1911 trigger is second to none.When I get the time I'll probably get a EGW FPS and put small radius and taper on it.If done right it works well.If you mess it up your out the low cost of the part.Having a gunsmith do the work would probably work for sure.It is said to help reduce recoil and muzzle flip.Many 1911 users do the mod.Recoil doesn't bother me in 10mm.Shoot a 454 Casull and then a 10mm it seems tame.

That's a good point.  So many current non-10mm shooters want to use 9mm as a baseline for recoil.  Makes no sense.  The 9mm is the weakest round available that still meets FBI protocol in choosing a round for defense.  The 10mm might take a little more practice than something like 9mm to control, but the 10mm is by no means uncontrollable.

   10d hold of on the EGW flat bottom. I purchased one from them and they sent an 80 series. As it turns out when I had the stocker out it virtually is flat bottom. I didn't opt for them to send the 70 series after this and instead got a fancy guide rod cap in place of the right one. I have a thread on here with pictures of both.

A heavier recoil or hammer spring may be money better spent. I don't see a Razorback under $1600 now
