Funny, I'm sitting here with my P11 in my jeans pocket and it draws pretty quick. You must DRESS for the gun. Ever wear a pair of carpenter's jeans or perhaps Wrangler cargos? The front pockets have plenty of room for a P11 and pocket holster. Hell, I often carry a bigger Taurus M85SSUL .38 snub in those pockets. Lots of people carry 642s in a pocket.
The P11 is 14 ounces unloaded and more compact than a J frame. Anything much over 20 unloaded and I find it uncomfortable to carry all day, just personally, YMMV, but I know a M36 Smith is too heavy for me and a SP101, forget it. And, I have a 12 ounce .380 I don't carry because the 9x19 is so easy to carry, why should I settle for a 90 grain Hornady XTP at 190 ft lbs when I can carry a 115 grain Hornady XTP at 410 ft lbs? With the 9, I'm reasonably certain I can get expansion AND enough penetration. It might not matter in a given shoot, but call me crazy, I prefer the power if it's not too much a trade off. And with the 9, we're talkin' light .357 power, or some .357 snub full power loads without the flash bang OR the recoil. I call that GREAT!
If I'm going to carry a .380, it's going to be because it's a lot easier to carry in the dress I'm forced with for the day. We're talkin' LCP/P3AT here, not Bersa. The Bersa has no advantage on my P11 as a CCW, none, not power, not accuracy, not reliability, not capacity, not concealability, not price, none. That's why I don't have one, though they are good guns I have no doubt and they're quite affordable. If I suddenly contract arthritis in my wrist, I may change my mind, but for now, I don't own a Bersa. I do have an LCP in my sights as my next gun, but I probably won't carry it, much, just want the option in concealment between my P11 and my NAA mini which I don't like to carry as a primary for obvious reasons. Lord knows it's concealable, though.
As far as shooting the P11, I've fired a lot of rounds through it. I normally put 100 rounds in a range session through it. I've fired all the available cheap off the shelf 115 ball ammo for practice, but one of my favorite practice rounds is no harder on me than .380. It consists of a 105 grain cast SWC sized to .357 (Lee mold) loaded over 3.2 grains Bullseye for 1110 fps chronographed. It doesn't lead, it's light enough that the brass piles up at my feet, but it's 100 percent feed and ejection. It's easy on the gun, and it's very accurate. I also load this same bullet over 3.6 grains Unique in .380 for 920 fps and it's quite accurate. The bullet is free (lead is free from the range backstop). All they cost is a primer, a tiny bit of powder, and a little time with my Dillon progressive. Now, for the non-handloader, this ain't an option for practice, but it works well for me and the 9x19 recoil is little worse than a .380, probably less than a .380 from a smaller gun.
