Title says it all. This is the only semi auto handgun Harrington and Richardson ever made. Made in both .25 and .32 in the 1910s and 20s. This one is in .25 and has a low number serial in the 8000 range. Not in too bad of shape for its age but has some finish wear thoughout. Very small and handy. 6 round capacity. I've shot a bunch of boxes of .25 through it over the years and it has functioned flawlessly in the last two boxes I shot through it recently. 300 OBO. Located in Cedar Park. text me at 513-419-9320
