Like the idea of 45 size hole in the barrel without corresponding increase in glock size over other pistols. Only concern is finding brass, ie once fired etc. Do the NYS police still use the gap? Do departments they sell their spent brass? Are there other issues to consider re the GAP glocks, will they fit my other glock holsters ie for G32, 27 etc. My only 45 is an ACP and a 1911. To big, too heavy to carry. My favorite Glocks are the compacts and sub compacts. Any other advantages/disadvantages to getting a Glock Gap? Is it worth using GSSF discount vs a typically more expensive glock or are the Glock Gaps still typically selling at same prices as other comparable models?
