Will be a 29 for me! I ordered it from Top Glock, hopefully it will get here this week. A few qestions for you: What # Wolff recoil spring would be best for heavy loads? I ordered a 23, too heavy or O.K.? Now that Top Glock has my FFL's info, I can just order what I want and head down to pick it up. No faxes, nothing to mail etc. This is almost too easy, I'm going to end up in the poor house but at least I'll be armed. Also, what kind of velocity loss do you get with the 29 vs. the 20? Do the lighter or heavier bullet's lose more velocity on average? Anyone here use a custom length barrel in their's? I was thinking about getting an aftermarket cut at 4" even. Maybe get a few more FPE? I'm a junkie, I know. BTW, my last Glock in 04' was another 20. Good shooting.
