guns would fit in the smaller hands of women -- this was the early 80's and active recruiting to make up for past wrongs, along with moving up from revolvers
That's the biggest problem I have, small hands. My G20 went to Robar for a grip reduction, works wonders. I would never of picked up this P226 if I hadn't shot my buddies new P226 in 9mm with Sig's new E "squared" 2 (I think that is the name) grip. The gun I picked up is going up to New Hampshire for this grip reduction. That's one reason why I liked the P220 so much, single stack thinner grip. I'm still ahead of what I'd end up paying for a new Sig with this new "E" grip out of the box, considering the stainless frame is what interested me (actually still ahead even if I add a .357 sig or 9mm barrel to put in that P226, so I actually have three calibers to work with).
Lots of info out there at the argument level
For myself, it's not about the "biggest baddest" caliber you can shoot, but being able to have fun putting holes where you want them. IMO if the gun you're shooting with isn't fun to shoot, chances are you aren't going to shoot it that much. Good practice makes perfect. I've seen too many new people buy a gun on the advice of their friends / boyfriends, only to get discouraged because they aren't having fun because of the larger caliber round they felt like they had to buy. I'd rather shoot a .22, have fun and get great groups than a 9mm and not be able to hit the target. If you can't tell, I'm not a big fan of big bore, lightweight hand cannons LMAO.
Now, all that said, my personal favorite round is the 10mm, because I think it's so versatile. You can load up, or load down, and have one of the widest range of bullets to load to for compared to most other calibers out there.
Way I have it figured is how many LEO's actually have to draw their weapon in the line of duty? How many times have LEO's discharged their weapon only to hit the intended target less than 30% of shots taken? This isn't a criticism on my end, only pointing out that even if you practice and practice putting holes in paper, it's different when someone may be shooting back at you. I still remember the advice given to me a long time ago... "paper targets don't shoot back".
