45 GAP is to 45ACP, like 40S&W is to 10mm.
While I'm not a huge fan of Glocks, only because they dont fit my hand well.
I appreciate the thought they put into the 45GAP. In fact I think Mr. Glock will be having the last laugh over this little invention.
From day one this little cartridge has been created and marketed for the LEO's and the like. If you think about it, its really quite smart on their part.
Many, many LEO's and various groups and been saying that they want more power than the 9mm offers, we hear it all the time. Many want to go back to the 45's, be it Glock in 45 or some other platform. The problem with the 45 has always been the size of the gun. Much like the problem with the original 10mm pistols, they are just so big(not to mention recoil in 10mm).
So the solution was to find a way to launch a 45 from a 9mm frame.
Enter 45 GAP.
What makes this even better for Glock is that they already have a HUGE chunk of the policing market in 9mm and 40S&W. Now they can offer the famous 45 man killing, baby saving, born in the USA bullet in a platform they are already familiar with. All Glock has to do is wait for a department to "life cycle" or upgrade the sidearms. Nobody has to learn a new platform, learn a new system, take a course, etc. In fact it really is no different than changing the contents of a pepper spray bottle.....the bottle stays the same.
