kraig,
You are missing out on a good gun. My G21 is stone cold reliable and one of the most accurate .45s I have ever shot. You can state your feelings 15 times as fast as you can pull the trigger.
A G21 with a 3.5 lb. trigger is a joy to shoot. I have several .45s ( S&W, Glock,CZ, XDM and Sig ). The Glock, by virtue of size is probably the softest shooting and easiest to rack.
I hear a few complaints about Glocks in general but it just goes in one ear and out the other.
I bought a Glock for my daughter when she went to work for the agency and she bought another after she got to Virginia. My son has two and a G30 is his carry gun and he CAN shoot that thing.
I shoot regularly with an LEO and a Glock 22 is his duty gun and he has another as his BUG. His wife is in the same PD and the same for her.
They recently were issued new guns and this guy and his wife drove to Prescott to buy back their duty gun trade ins.
Give it a try. I really think you will like them. A Springfield XDM is a very similar gun with the advantage of interchangeable backstraps. The trigger on my XDM is decidedly spongy up to where it locks up and is ready to go. The Glock is much better. I have not fallen out of love with the XDM but it is not my favorite.
The thing about the Glock is it runs best with not so much lube. Follow the Glock manual and you will not go wrong.
Let us know what you find out. I read your posts with great interest and would value your input.
