I have a Heckler & Koch P30 V1 with a minor but annoying issue. When I squeeze the grip firmly (not a death grip, mind you, but firmly), the backstrap moves / depresses a little. I don't think it is affecting my shooting, but it does annoy me when I am dry firing, particularly strong hand only.
I have tried
- Switching backstraps
- Switching side plates
- Checking to make sure the side plates are properly seated
None of those has helped. Any thoughts on how to fix this, or is it not fixable?
Edited to add: I should probably note that I have a P30SK that does not have this issue at all.
