Anybody use them much? Been eyeing the taraus pt 140 for the longest. Looks like they've finally got all the deficiencies worked out with the 3rd generation.

And I really like the 40S&W for a self defence round. Heavy like 45acp, yet fast like 9mm para.

If I were going to have a DAO, I'd stay with a revolver. The DA stroke is smoother and generally lighter leading to better accuracy. I prefer either a Glock for consistent trigger pulls in a semi auto, but it really isn't a true DAO, or something like the Browning High Power for a Da to SA operation.

Let me specify and say that I meant automatic pistolet. I doubt I'll ever own anything smoother in DA than my dan wesson.

Also, is the pt140 really double action ONLY ? I mean is it really never cocked, or does the DAO just apply to the first shot?

I've rented quite a few pistols at the range the past year. For some reason, I really like the .40 round. I respect pistol DAO but prefer single action Kimber and STI.

Glock supposedly doesn't have the best chamber support for .40, or something like that. Springfield XD 40 some say is better choice than Glock.

Based on what I've seen in the Model 94 .22 revolver, I'm not impressed with Taurus. Others praise Taurus. Probably depends on the model?

mav... did you just say that you liked the browning high power for it's double action to single action trigger? By that I assume you meant the way a double action has the long pull for the first double action shot and then a short one for the remaining single action ones?

If so.. I made the same mistake here about high powers... it does look like a double action huh?

My excuse is that I never use the double action feature on da semi autos.. I allways thumb back the hammer.

Halo, what does this statement mean? I own a G27 in .40 and have been having problems with chambering. Evry so often, I get a round that jams as it's loading into the breech. The feed angle is very steep in the g27 and the round jams; on the bullet itself, not on the casing, upon feed. This causes what I could only describe as a half-****. The slide is left open a 1/4 of an inch or so and I get a dead trigger. I've tried different ammo thinking that was the problem, but still get same problem. It doesn't happen alot, but enough to bother me. I also thought I might be "limp wristing" the gun and robbing the action of the energy needed to cycle, but that isnt it either.

Any thoughts?

Porkfrog, I came across that assertion many times while researching various gun items. Google for .40 cal Glock chambering or something like that and you'll find many references.

Here's one, not the best, but typical:

(quote) In the end, I was leaning towards the Glock. My only issue is that in the .40, the Glock chamber is not fully supported. And while Glock owners will tell you that (It's not an issue) it is if it's my hand that might get a case failure on upwards of a kb!. This is especially true in the .40, the 9mm and .357Sigs all have supported chambers, but not the .40. So I would buy a Glock but for the fully supported chamber and spongy trigger. They say that I can get a new barrel from BarSto that is fully supported, but then that would put me in the price range of a Sig, and then why wouldn't I do that? They also say that I can shine down the internal trigger parts and make it a lot smoother. (unquote)

all in all i absolutley love the gun. i don't care about the trigger arguements, it works and feels just fine to me. however, i do strongly dislike this chambering issue. i had a few diehard glock fans at the range try and tell me a dozen different reasons why it could be happening, but none of them included a design flaw. they more or lessed blamed me, or the ammo. i'm no novice shooter, but i'm not a gun nut either, and simply recognized that something wasn't right.

i am military and paid 100US less than retail so i guess i could opt for the better barrel. i don't like it, but i guess if that fixes the problem. i just would really hate for this chambering issue to arise in a real crisis when i was depending on the gun to save my life, or that of my loved ones.

I have even heard that you are not supposed to reload brass that has been through a glock. No matter to me since I don't shoot the 40 Short $ Weak.

If you get a barstow or similar barrel with better support.. you will not have the reliability of the glock barrel... something about the 40 makes it not want to feed as well as the bigger 45 or smaller 9

FWIW the .45 colt also doesn't support the full case. Part of the case web is exposed by the cutout on the bottom of the chamber area from the relief cut on the chamber feed mouth. This kind of thing only becomes an issue with an over pressure load. That's a way over pressure load by trying to make a magnum out of basically a short caliber round. As long as you use normal pressure loads, be they factory or reloads you are not going to have a problem unless you get a faulty case and that is bad news no matter what kind of chamber you have in an autoloader. It is also very very rare.

mav.. that is correct. so far as it goes.

The 45 is unsupported much as the 40 short and weak but... the 45 is a very low pressure round. the 9 mm is supported and a high pressure round.

The 40 is the worst of both worlds... it is unsupported like the 45 but high pressure like the 9mm.

I have heard that it is not a good idea to reload brass that comes out of a block 40
