I typically just shoot standard pressure. I just don't feel the need for +p. My typical carry gun is a G26 and I've never even tried +p through it. In fact I think I've only ever put one box of black hills red 124+p through my M9. Which you can tell the difference but again, in that gun it's not bad.
I'm too cheap to buy new, expensive grips for every pistol I get. I probably would like something better, but it's not high on my priority list that doesn't have a lot of extra money anyways..... I probably won't buy anything wilson combat for my M9. I like how the safety makes the one side smaller but I don't like how it sticks out on the other side. Although I guess it's not much different than having a safety on that side.
Actually, I kind of like the standard safety because when I'm gripping the gun, if the stock safety is down, my thumb can almost feel it where I normally grip. Just a tiny bit of movement in and oh, I feel the safety and flick it up. I'm a little concerned with the wilson safety that it's too low profile and if I ever do accidentally engage it, I won't ever know until I'm starting to pull the trigger. No good.
Yeah, I wish it was a G model.
