My background : New shooter (since last November): Range practice once a week 200 - 300 rounds slow firing and point shooting (12' to 21'). I have G19 (gen3) and G30. Before the purchase of those two, I had a 1911. I wanted to get G19 (for lower cost of ammo), and I was going to get G30 eventually. However, I ended up trading 1911 for G30 (came home with G19). I shoot better with G30, I pretty much stopped shooting G19, and I will trade G19 for my next purchase. I want to stay with the same frame size as G30. I wanted to get G32/33 but I changed my mind due to different frame size. My list of future purchase is: Gen4 G21 G29 (plan to get conversion barrels for. 357sig & .40) Many members here were very pleased with Gen4 G21. I had a feeling that I would like it but I am be afraid of grip/frame size being different from G30. I am thinking getting this later, maybe Christmas time. I am leaning toward to G29 but undecided to go with either G29 or G29SF. If I get G29SF, and if I like it, I would want my G30 to be G30SF. If I do not like the G29SF, I want it to be G29. Any inputs would be appreciated.
