My 15 year old grandson, who is in the ROTC, in high school, practices three times a week in school. They use Crosman Challengers and compete with all NE high schools.
James in basic training I was one of three that qualified for OCS but when they told me I'd have to do four years instead of 2 years I said no way.
Here are the 2 different hammer pins I have. I tried the thicker one but without making the counterbore on the hammer deeper it won't slide in the tube under the pin slot.That said, I'm not sure if drilling the counterbore deeper would let the bottom of the pin interfere with the spring. I think tapping the hole and make a new pin would be the best option. You won't need a shoulder on the pin if you use thread locker.BTW... I think the thicker pin is from a 2240 hammer.

I get rid of the slop in the hammer pin by holding it upside down with needle nose pliers or vise grip on anvil or hard surface and lightly peen with a ball peen hammer the short bottom section of the pin. Just a few light strokes on the soft metal will peen it for a tight fit. If too much just file or sand it until it goes in for a tight fit.

Did you know?......I decided to go back to the 18" .177 barrel on #805. And use that Ruger rear flip up cross notch peep...https://www.midwayusa.com/product/1005064221?pid=186476I described how to install it above.Well, as you can imagine and I also reported above, the 18" barrel only extends 1/4" beyond the front of the barrel band.... it ends up looking much like a 392 barrel. But it leaves nothing to hang a muzzle break or a front sight on.I'd really like to keep this gun a little compact critter gitter.I just happen to be looking around on the bench and spotted the plastic bag containing the leftover screws and spring from the Baker brass trigger. Sure enough, those adjustment screws for the Baker trigger are the exact thread and Allen wrench size as the grub for the front barrel band. And even better enough sticks up to be near perfect for a front sight blade.Even better.... I had bought 100 .177 bolt o-rings so I stacked 5 of them on the screw to make it look much better than a raw grub screw sticking up. I left maybe a 1/16" of the screw showing at the top.Camera battery was dead so I'll have to post a pic later.
Mine got the soup can test today
