Yea that's just the thing no tools are required to break the 22/45 down , none . The only thing that I can think is the issue is the steps and order in which the steps must be done . Once you get that down your good to go .
I kinda equate it to someone saying they don't want a 1911 cus there so hard to field strip and put back together . Well yes they are compared to a glock or XD but in the hole grand sceem of things it's really not that bad just a couple more steps . By doing so there missing out on a very good gun .I don't know maybe all the 22/45s are a little different and some are harder the work with then others .
I have no problems with mine .
Why do I carry a 45 ? because they don't make a 46
