9mm (+P+) in Glock 17 and CZ?

Don't know about CZ, but I definetely wouldn't shoot +P+ in a Glock. Unsupported chamber + high pressure ammo = kaboom.
 
9mm +P+ ammo......................

Good to go in a Glock. Probably ok in an all steel frame like the CZ. Wouldn't do it in an aluminum frame like the Beretta, though.... :eek:

Well, since the 9mm chamber in a Block is fully supported, and the gun is designed to run 9mm NATO ammo, which is +P+, I've got to say I disagree with you! :)

I agree with Lugger. G17 may have more support than .40 and .45 caliber Glocks, but I would not call it "fully supported".

An example of a fully-supported chamber is on the right (Bar-Sto). Stock Glock 17 barrel is on the left.

what does the frame have to do with anything? ;)

I've shot some warm relaods as well as NATO ammoin my 92 and never had any problems.

btw capp are you sure that barrel is factory Glock? It looks like stainless...

My bet is with a steady diet of +P+ 9mm's thru a Beretta the frame will prematurely crack.... Just the reason PD's that went to Berettas in .40 S&W found out. Aluminum + high pressure loads = frame cracking. Not 'if' but 'when'............... Your mileage may vary.... :D

Is probably gonna happen in a steel frame eventually, too............

Just my .02............................................................................
 
Correct me if I rong... but doesn't Glock proof test all their pistols? Hence the nPv proof markings. The EU ones anyway. And IIRC, they fire loads at double+ the limit??

I would go over to glocktalk.com and ask/look there, but from what I have heard... no probs at all, but parts might wear quicker if shot frequently.

I would love to get a hold of some Winchester Ranger 127gr +P+ though to try out. They seem to be one of the most popular JHP's. Even some Double Tap or Corbon.
 
I would avoid a steady diet of the +P+ loads in a handgun except maybe a gun built to run 9mm major. Pressures are starting to get close to proof loads and will certainly pound most handguns.

Beretta's are all tested with 10rds of high proof rounds at the factory. The man performing the testing wears anti-fatigue gloves at all times. After testing, the guns are stripped, cleaned and then magnafluxed for cracks, cleaned again, reassembled and lubed, then boxed for shipping.

Would I use +P+ in a Beretta? Yes, but not a steady diet.

Would I use +P+ in a Glock 17? Yes, again not a steady diet.

+P+ is just a wee bit hard on the body, recoilwise.
