Lots of direct experience with Glock 19s. Excellent pistol, suitable for a variety of uses, including CCW.
I have shot a number of compact and sub-compact 1911s, but haven't owned any. From what little first hand experience and from experiences shared from trusted friends, compact 1911s can be finicky. However, like any mechanical device, assuming proper maintenance and time/effort for tuning, can be fine. Main take away for me is does prospective owner have time, willingness, and inclination to perform the tuning and maintenance? I certainly do not.
