Well heres the big question, "Should i buy a gen 4 G19 or even a GEN4 G17? I have a G26 and G23 since 2002 and I "NEVER" had one single FTF, jam, anything!! Flawless for probably over10,000 rounds and counting! Eats any type of ammo! So I read countless articles on the GEN4 issues with the G19 and G17 recoil spring! Brass in the face, stove pipe, ftf, etc! Glock is like on #4 spring replacement, also heard that it is not the spring, but the extractor!!! The proven extractor # is #336, and looks like the flawed extractor is #30274. I am hesitant to purchase one at this point! I love my Glocks and never heard anything bad until the Gen 4 era hit! My friend has the S&W M/P 9mm and said it is great! I actually looked at one at the gun shop today! This is the first time I looked at another maker other than Glock! My son is 14 yrs old and loves shooting my G26! He told me buy the G19 or 17 Gen4 and nothing else! I guess he is loyal!! I wish Glock would have left the internals alone and just added the back straps! I went from wanting to buy a Gen 4 to sitting on my money and looking at another brand!! Any 1st hand experience with the Gen4 19 or even 17 would be helpful!!!
