What are your thoughts about using Corbon's 45 ACP+P 165 gr JHP 1250fps/573 ft/lbs out of my Glock-21. Is the gun able to hold up to the pressure? I like the energy.

I don't think I have run more then 20 rnds of Cor-bon 165gr through my G21, but I have been using 200gr Cor-bon's, and when I can find it 230gr Cor-bons for about the last 5-6 yrs. Of course, that isn't the only ammo I shoot, (just to "use up" older HD ammo, and to practice a mag or two at range sessions). I have had no problems, and have not noticed any damage/ peening of the slide or rails.

45 AUTO+P 165 GR. JHP 1250 FPS/573 FTLBS compaired to:

45 AUTO+P 200 GR. JHP 1050 FPS/490 FTLBS or :

45 AUTO+P 230 GR. JHP 950 FPS/461 FTLBS,

" Does Cor-Bon ammunition meet established pressure limits?
A. Every production lot is continuously monitored and checked every half hour during its production. Cor-Bon follows established SAAMI specifications. Loads not within SAAMI specifications are marked as such."

165gr is a bit of a jump, but I don't think any of these rounds would be a problem, except if they were the ONLY rounds you used, and you fired 200-300 a week.

Please note, I am neither a firearms expert, or a ballistic expert, and I did not stay at a Holiday Inn last night.:D

I don't see why it wouldn't be safe. Despite people running around with their hands in the air screaming that the sky is falling because of "inadequate case support" and such, Glocks aren't fragile. In fact they are pretty durable. If you are really concerned about it and intend to shoot a steady diet of them, install a heavier recoil spring. They cost like $10.

Don't get too caught up in energy. You need to consider other things as well. This is coming from a 10mm advocate so I know how comforting it can be to lull yourself into a false sense of security because of energy. Foot pounds has its place. But bullet construction and mass should also be considered. In particular, the 165 gr .45 caliber bullet is not, to my knowledge, known to be a steller performer. Very low sectional density, which when combined with its construction and velocity could lead to inadequate penetration. The Glock can handle it just fine but you might be better off going with something a little bit heavier--like a 185 or 200 gr--even if it has a little less energy, it is likely to penetrate deeper and use that energy deeper in vital organs where it does the most good. My $.02.

The g21 frame was designed for the 10mm, so yes it will handle the factory load. the g21 is able to handle the 45 super with just a spring change.

CorBon also has a 165DPX none +P compact that 1050 from a 3" and oner 1100 from my Commander. I have in my compact and commander both.

How much heavier of a recoil spring would you recommend for the G21 with +P ammo. I was thinking about buying a 20# for all around use. but like everything it will take some experimentation. Any thoughts?

As much as you're going to be/can afford to be using it I'd say it's alright, but honestly I'd go with a 230 Gr. HP out of a full size pistol like yours. Just my .02, I've owned a Glock 30 and it pretty much digested anything. But as a rule, I go with lower grain in a subcompact w/ shorter barrel, heavier in a full size w/ longer barrel.

I carried a glock 21 for duty use for years, that gun will handle any type of commercially loaded ammunition you can find...it won't strain it a bit. I called Glock in Smyrna and asked the tech guys a few questions, one of which was about any particular ammunition they knew of that performed better/worse in the gun, they said and I quote..."Any quality commercially available ammo is absolutely fine. The gun will handle any +p round you can put in it with the only difference being you might wear out the recoil spring in 40,000 round instead of 50,000. But for practice the gun performs better with hotter ammo like Blazer, winchester white box may sometimes short stroke the slide." This is probably why new glocks come with the test casings from Blazer rounds and not something else. Besides all of that...unless you win the lottery no one I know of could afford to buy enought +p ammo to wear out a glock.

I've used Corbon in mine although I prefer Hornady TAP, like sokygunner said, the Glock will handle any factory load you feed it in its stock configuration.
