Just purchased a Glock 38 and have replacement parts questions. It I want to change the sights, recoil rod, connector, and trigger spring do I order the same ones as the 19/23/32? Also, is the stock recoil spring poundage good or do you guys run extra power recoil springs? Lastly, does a +2 base plate only hold one extra round of GAP? Thanks for helping the new guy.
