The Colt Mustang, Sig P-238, and Kimber Micro are all very similar mini clones of the M1911.
My 1980's vintage Mustang is as reliable as a light switch. I do not know about the current manufactured Mustangs or the polymer frame version.
My first year production model of the Sig P-238 had some teething problems. It is now fixed. I understand Sig has fully corrected the first year faults.
I have no experience with the Kimber Micro--yet.
The Colt Government 380 preceded the Mustang production in the 1980s. A bit larger than the Mustang. Also, good shooters.
Colt M1908 pistols are great shooters and an SA pistol. It's the 380 ACP version of the M1903. These are a bit larger than Colt Government 380. I believe the M1908 was manufactured up to around WWII.
The Beretta M84 (double stack magazine) or the M85 (single stack magazine) are SA/DA pistols but can be carried cocked with the safety on, at least the 1980's versions. My M84 shoots about anything that I have fed it. With the open top slide, jams on ejection are virtually non-existant.
