I have been carrying a Glock 19 for a long time because of my tactical energy storage device (belly). I made myself a deal that if I lost enough weight to carry a full sized Glock without terrible printing I would buy one. Being that I have a few glock AIWB holster around the house I cut the bottom out of one to try my Father's Glock 34. It actually went quite well.
Here is the question, is the Glock 34 worth the extra money and buying a new holster over a Glock 17? Should I even bother with a full size? I have started just running 17 round mags in my G19 anyway. Last option is way a few week or a month and be another gen 5 beta tester.
