I carried a Glock 21 for 9 years on the road before going undercover and would say that if I had to go back to uniform and a .45 was required it would be a hard choice for me between e Glock 21 and the HK 45. That being said I was issued a Glock 36 for a backup weapon and during the 12 years I had it I never cleaned it and only shot it during qualifications as the gun never felt right for me. Needless to say it never had a malfunction of any sort I just be never cared for the ergonomics of the gun. I would buy one if it fits your hand and it meets any other criteria you might have.
