Where they hard to put in? I've done glocks but wasn't sure on these.I’ve used them with P07, SP01, and FN509 I saw a huge improvement. I do recommend using these springs
I would watch an installation video first and see how confident you feel on installing the springs. I like to think I can fix everything, but that’s always the case. Installing springs on certain guns sometimes becomes aggregating, but others are easy. Take CZ (non-omega) & Sig P229/226 for example, they are more difficult to work on than P-320 or Glocks. Glocks are hands down the easiest, most simple, ones to work on. I say go for it and if you run into a snag, I’m sure someone here would helpWhere they hard to put in?
