I inherited this gun. My grandfather got it in 1928 (its engraved with the date). He was a Chicago cop. If I measured right it has a 5" barrel. Any idea what model and where I can get a decent holster?
It's a Military and Police Third Model (also called the Model of 1905), Fourth Change. It chambers .38 Special, right? If it is dated 1928, it probably has a serial number in the 575000-600000 range.
Nice ivories. The gun looks to have been reblued because a couple of the pin ends look a little flat and the edges of the side plate are a little soft from the pre-blue polishing. Also, most of the barrel markings have been polished out.
Any K-frame holster that accommodates a five inch barrel would do the job. If you find one you like, please don't store the gun in the holster; the acids in the leather can promote corrosion. It's OK to carry in the holster, but once you are home separate the two and wipe the gun down before storing it in a gun sock or some other safe medium.
It's great to have a firearm that is a family heirloom. My parents and grandparents were not gun people, and I envy those who have inherited firearms from LE or shooting-sport forebears.
And welcome to the forum. We're glad to see new faces here.
