An issue I've found shooting some very small pistols is the trigger sort of pinching my finger under recoil. As far as I can tell what's happening is the flesh of my trigger finger gets caught between the bottom edge of my trigger and the trigger guard under recoil. I've experienced this on an LCP II, a P365, and a PPS M2. My experience has been that adjusting my finger placement helps some on some guns, but not 100%. For example on the P365, switching to the tip of my finger reduced pinching a bit (in exchange for shooting a bit off) but on the LCP there was really no way I could mitigate it.
I found a small auto that I didn't really have this issue on, a Kahr CM9, but when it comes back from its second trip back to the factory I am getting rid of it, so I'm in the market for a small 9 again. I don't really have an option to rent the top candidates in my area, so I've been trying to sort of guess based on the shape of guns whether I'll encounter the issue, but I do wonder if there's anything I can or should be doing to mitigate this issue. This gun will be riding under tucked in work clothes in an Enigma, so unfortunately it'll have to be pretty small.
I'd really like to minimize this issue if I can, even if that means aftermarket triggers, because I like to shoot my carry guns every time I get to the range and I'm concerned about developing a flinch over time.
I don't have especially meaty hands but I do have long fingers, so I tend to sink a bit more finger on the trigger shooting small guns, especially in a hurrry.
Any recommendations in terms of technique I should try here? I've gotten very different responses from people on this about the same guns, so it seems to me like a hand shape and technique issue as much as an equipment issue.
