Model 52-2 Slide Stop

Register to hide this ad
I have a friend who bought a 52-2 with a missing slide stop.
Got a new one from Numrich. There are four separate parts that make up the slide stop. It is not a drop in part.
 
I bought a new one last year from JackFirst in SD.
Very expensive but it was new and complete. I tried a couple of used ones from Numrich and neither one worked.

I just looked at Numrich. Their price for a new slide stop is good by JackFirst standards.

This may be off topic, but I have always had problems with the action of the slide stop with magazines with plastic followers. All my mags. with steel followers work fine but most of mine with plastic followers don't.

It's definitely not a drop in part even as a whole assembly. Take your time when fitting it. Barrel to slide stop fit is one of the key areas for accuracy of the gun.
 
Hi, Don!

Would you care to elaborate and describe the operation?

TIA!

If the slide stop is new there could be a lot of material to remove. If it's a used stop it should be tried in the gun and there should be friction when barrel rides up on it. You can only hope for the best with a used one. A new one must be stoned a little at a time, a little wider than the barrel ramp, trying it often for barrel friction. A magic marker comes in handy to show where the barrel rubs the most. You want as much surface area to ride up on the slide stop evenly with enough resistance to cause the slide to "jump" into battery. Patience is in order.

Thank you, Don!!

If I understand you correctly, a new slide stop should have sufficient thickness to prevent the barrel from going all the way up into battery until it has been carefully stoned?

And since you have been so gracious, is the tail of the barrel hood where it meets the breech face fitted more tightly on the Model 52 than on the service pistols or is it done to the same clearance?

Yes, the slide would not close completely.

The Mod 52 barrel is fit so there is NO play at all, front to back, but will drop on its own. On any other guns I built while there, such as the 9mm's, There is no set clearance space.
 
Thanks, Don!

Yes, it was explained to me that the service pistols were also fitted to "drop".

Just as the slide stop is fitted to cause a little "hitch" on lock-up on the Model 52, I also wondered if the barrel to breech fit was also a little tighter, but apparently not.

Was slide stop fitment as precise on the service pistols with which you were associated or (as I expect) a different specification?

The mod 52's were hand fit, each part unique to each specific gun. To some extent the Mod 41's were also. The 39-59's were assembled, most parts are interchangeable. I think I mentioned before that I used to build less than twenty Mod 52 guns a week. When I went on to build the other autos, we would put out 50 or more guns per day.
 
Thanks again, Don!

If my calculator is correct, that works out to more than 2 hours to hand fit a Model 52 versus less than 6 minutes to assemble a service auto.
A fascinating comparison.

Your "insider" information is a valuable asset to this forum.

I would much rather listen to an experienced insider opine about the coffee in the break room as listen to 1000 keyboard commandos lecture me what should or shouldn't be on gun design.
