That sums it up. Now that years later, Glock realized they don't need a 10mm slide on a .45, and have put a 36 width slide on their 30. The thing is actually nicer in its lighter version. I don't like the clunky lookin extension though, it would be soooo much better if it had a G19 like grip, where you could get a full hand on it and flush fit mag. I hope they put a thin slide on the 21, 38, and 37. I think the GAPs would move alot better if they had a thinner slide, cause at that point it would be like you had a true G19 in .45!!! I still want a single stack commander size. Dave Wanna kill these ads? We can help!
