    My mom's aunt gave me a H&R 733 that is hers to clean up for her. Nice pistol, not bad for her needs. It is double action only. It says on the barrel "32 Smith & Wesson". Would that be S&W long or short. I ran some shorts through it, and after 3 or 4 cylinders full, it will begin giving light primer strikes that will not detonate the primer. However, if it is clean as a pin, there seems to be no problem. Any ideas on that?

    Thanks in advance.

    It is chambered in .32 S&W Long.

    Misfires could be caused by old ammo.
    Or mechanical problems with end-shake induced excess headspace.
    Or a weak hammer spring.
    Or dirt & unburned powder under the extractor star cushioning the FP blow.

    Some of them also were made with a plastic main spring guide rod, and they sometimes fail.

    Numric has new main springs for about two fifty.

    The firing pin channel can also be a problem. So that might need to be cleaned out as well as the other problems the guys have already stated.

    The 732 and 733 are handy little revolvers, and there's not a lot to go wrong with them. Deterioration of the plastic guide for the mainspring seems to be the main complaint that comes up, but there are all-steel replacements available, and it's simple enough to do yourself.

    Other than that, just keep it clean and oiled, and it should be good for another 40 years.

    Reading your problem exactly as you posted - it sounds like an ammo problem rather than something mechanical. If it fires 3 or 4 full cylinders full with no problems - then begins to give light strikes after that - then I'd suspect that you're getting cylinder bore fouling from shooting the shorter .32 S&W cartridges. The shorter OAL allows some build up in the "empty" part of the bore which eventually keeps the rounds from fully seating - the hammer then expends some of its kinetic energy pushing the cartridge home.
    The Model 732/733 was in production from 1959 until 1986 and was a very popular item for H&R. From '59 up to '73 it was equipped with a spring buffered, frame mounted firing pin and from '73 to end of production it was equipped with the transfer bar safety/ignition system. If the gun shoots OK when clean - then begins to misfire after a couple rounds through each bore - get some .32 S&W Long cartridges and try them. If the problem persists - re post.
