Yes, the pin required way more force to remove it than I thought it would. Even pushing the end on a piece of steel didn't seem to move it at all, like it would with most other pistols. Putting it in was easier, but it still required a few good hits to put it flush. It is almost like the recess is not deep enough to allow the pin to freely slide in.
FWIW, I put the Comp spring (#13) in and didn't find much difference in my DA trigger pulls; I have the full-size 4.9" INOX version.
Blade-Tech, works well.Which holster is that and how'sit working for you with the Compact?
