    I randomly found and snatched up a Steyr GB a few weeks back. The gun is an earlier commercial variant in overall great shape, the gas system and vents clean, the gas cup snugly fit, and the recoil spring feels appropriately strong. The internet videos I had watched on it seem to conclude broadly that the gun had relatively soft felt recoil, but I noticed mine seemed much sharper than many of my other 9mms. Some slow motion video revealed that the slide velocity on the GB was much higher than the other guns. A closer inspection of the internal parts showed no damage other than a few nicks on the very rim of the gas cup that correspond to the peaks on the barrel nut.

    Finding other folks with GBs for comparison is a bit tricky, but this forum seemed a solid bet. My questions are thus:
    1. How are other folks experience with the recoil? Mine seems quite linear feeling but also a bit abrupt. Is this indicative of something being more wrong than it seems, or is it normal when compared to locked breech guns?
    2. Are the nicks on the gas cup normal wear and tear or indicative of something worse? They are small and not impacting the gas seal part of the cup, but I have nothing to compare it to to know if it is normal.

    If anyone else here has a GB and can check it out to compare to my results, I would be much obliged. Thanks.

    Here is my GB gas cup. 1 small nick like yours. Mine is the military trial gun. I never fired it so I don’t know how the recoil feel. May be put some grease to make it a better deal?

    I don’t think It was fired before.

    Thanks! I have shot it a few more times - about a box at a time, and checked for any change in the internals. None so far, so if there is an issue of a weak recoil spring or something, I don't think it is yet self destructive. I don't expect to shoot it a lot anyway thanks to the snappy recoil, less than good trigger, and the time it takes to clean.

    If I may ask, does recoil feel less after 5 rounds? If so, it usually means the gas seal is not tight enough. One option is use the high temp grease close to muzzle end of the barrel to get a better seal. I remember you replaced the hammer trigger already? Yes, GB trigger is pretty bad da. Sa is ok, but not good either. You are right, cleaning is a little more pain vs the newer pistols because GB is fixed barrel.

    I have not paid close attention to see if it has changed... interesting concept. I will have to see how it differs next time I shoot it, but so far, if there has been a change a few rounds in, it hasnt been big enough for me to notice it. I have not replaced anything on the gun as of yet... not even sure where I could find spare parts anyway.
