Which caliber do you prefer? Why?

[Flash]

.45 ACP because I shoot it better in my P220s than I shoot 9MM in anything else.

Mostly 9mm these days. Being the tough guy many years ago shooting every hand canon I could buy or borrow has left me with severe nerve damage in both hands and extending up to my elbows. Full size pistols now and I prefer heavy steel frames. Hand pain has got me back into 1911's again as they don't hurt as much as a plastic pistol.

I shoot 9mm suppressed but carry a 45 Shield and have a PPQ 45 bedside HD pistol. These two are very soft shooting and easy to be very accurate with... for me. YMMV

Now this 1st run G21 (with antique red laser) is not one of my favorite .45 pistols to shoot.

I prefer .44Mag. My dad had me shooting his Ruger Super Blackhawk when I was about 6 and I fell in love. In addition, I love shooting a big heavy bullet and if I ever had to protect myself, I want to make sure they'd go down on 1-2 shots. I do own several 1911 .45 ACP's and several .357's too.

9mm is my go-to these days. I still love .45 - back in the day I had a couple of Canada-made Para-Ordnance .45s, including a P12-45 for carry, before I drank the Glock kool-aid - but for all the reasons stated above by others, 9mm just makes more sense these days.
I'll probably never stop shooting .45, though. My FNX-45 tactical is right up there with my favorite pistols... just not as practical as the Glocks.

Tuff choice between the 9mm and 45. I am pretty split down the middle but I do prefer reloading 45 more than the 9. But because of the AR 9mm I voted for the 9mm. Do they make an AR in 45?

[Crippledtrigger]

Oh yes! Many places make AR platform weapons in 45. I'm not sure if they are all dedicated/designed Glock mag lowers or if there is an adapter block for 1911 or grease gun mags. IIRC I think there is one for standard 1911 mags but that would seem not feasable cost wise. Especially with Glock mags and clones cheap and plentyful. The cost of the block and mags would seem too expensive compared to cheap lowers in pistol calibers. Still, I'm sure someone would want interchangeability over dedicated platforms.

9mm, The reason why is because I want them all the same caliber.

[John Kuhns]

This is a tough one for me. I carry the 9 more but still carry and train with .45 enough that it still has a place. Especially the G41 Gen4. Same with the P220s.

I go with 45 & 10mm.

My old standby is .45acp, but really am liking the .357sig. Shoots like a laser and hits hard.

I have a .357 Sig barrel for the Glock 22. Am probably going to give it a try this weekend. With 4 days off from work I should be able to find one day for a little trigger time.

[Gunslinger]

I like all the calibers listed but if I had to choose it would be 9 mm because it's cheap and easy to shoot.
