New Crosman Model

I stopped by my local WalMart store this afternoon to pick up some CO2 and saw what I thought was a 1377 in a blister pack. The price was right, so I brought it home only to discover that it was in fact a new model from Crosman, the PC77, Pumpmaster Classic. Although it has the outward appearance of the 1377, there are some very interesting differences.

First is the trigger. This model has the new wide blade metal trigger in a black finish. Also missing is the spacer between the barrel and the air tube. But the biggest difference is in the grip frame. This is a totally new design from Crosman and adds a few new challenges for grip makers.

The first change that I noticed was that there are now three screws that attach the side plate to the frame. The plate is now plastic, and the fit to the grip frame is much more precise. It fits totally flush with the frame whereas the older version stood proud of the frame at the top of the trigger guard.

Secondly, the post that holds the sear spring is square rather than round. I havent tried fitting a factory sear spring adjuster, but if the spring fits over the post, more than likely the adjuster will. Add to that the differences in the general geometry of the frame and grip makers now have to make a few changes to get things to fit.

I'm not certain that Crosman will change every model to the new style frame, but I'll have to keep it in mind for my future grip production.

My last observation of this model is that it shoots perfectly at 10 meters, whereas previously purchased 1377s were always shooting high at that range, regardless of how the sights were adjusted.

Michael,
If it's any help, my old buttstock fits the new 1377 Classic very well.

The 1399 Shoulder Stock and Stock Plastic grips fit fine

August 4 2010, 6:44 PM 

but none of my custom gripsets will fit without modification. The forearm will fit, but the Grips need additional inletting.

I just bought two of the spacers 1300A008 from Crosman, they were cheap. They are a necessity if using the Crosman barrel clamp scope mounts on a plastic receiver gun. Keeps the scope from twisting the barrel.

third screw

August 4 2010, 7:46 PM 

I like the idea of the new screw in the side plate I've been toying with
the idea of adding one on my guns just ahead of the side plate so that the
screw head would overlap onto the side plate. There is more meat to drill
and tap there, it could be a flat head properly counter sunk and still work
or let me guess "someone has already been there done that. I'd bet that one
of you has already thought of that one, though I haven't seen it.

did they change the rear sight?

August 5 2010, 9:24 AM 

i have noticed the same thing on every 1377 ive ever shot, even at 20 yards the rear sight wont go low enuff, i usually use a dremmel to elongate the elevation hole. so im guessing they either are using a lower rear sight or have hightend the front sight??? i really hope they have a new and better rear sight now. please let me know.

Very Similar Design To The Maurauder Pistol Prototype

Great information and nice photos Michael.

The PC77 frame design appears to be very similar to the Crosman Marauder prototype.

As seen in these official Crosman videos:

Plastic

August 5 2010, 10:33 AM 

Maybe the new plastic side plate needs to be secured a bit better than the previous metal side plate (3 screws vs 2)? Didn't they change the valves from brass to aluminum a while ago? I guess it's all cost cutting to keep the price down. I hope the trigger doesn't go plastic next. Maybe the entire grip frame will be changed to plastic. Buy up the old inventory while you can...lol happy.gif

Cheers,
Todd
