Do not try to keep up with the latest toys...unless you have lots of money.
I started with a stock 1911....then G21...then Para 16/40....then back to the single stack. It is more fun and if I do my part(reload), I can shoot very competitively. The 45 kicks less(IMHO) and cost less to maintain. Glocks are good to use, it just depends on what you shoot better. My single stack just keeps on going.
