Picked up a 4" bar model 10 from aim a few weeks ago. Besides being full of sand I am happy with it for the price paid and for the amazing SA trigger. But the danged thing will not chamber a 38 SPL cartridge! They only go 3/4 of the way in. Upon further inspection past my initial cleaning it looks like there is an insert in the cylinder chambers so it could shoot a round with a shorter overall length. It reminds me of the cylinder machining in my 45 acp Vaquero. Looks like it will allow a non rimmed round to head space off of it. Could it have been converted to 38 super or some type of auto rim? Or possibly 38 long Colt? Barrel is marked 38 S&W Special.

Oh yea don't be jealous of the F4U band aid

Does a 9mm fit?

9x19 case has too much taper to fit.

No idea then.  I thought it may have been set up for 9mm and moon clips.  If the 9mm has too much taper, then the 38 S&W is ruled out as well.  Nothing else makes any sense.

I was thinking 38 S&W also. I may have some brass floating around at the house to try. I also doubt it would fit.

Got any idea where that revolver came from?  The gun was most probably a dedicated lazer training gun and the inserts put there to make sure no one mistalkenly loaded it. The lazer module goes in the barrel and is activated by the hammer fall...they should come out with little problem if that is the case.

The inserts do not make a full 360 of the cylinder so the probably rely on spring pressure to hold them in. Another thought I had was simunutions but wrote that thinking I was crazy.

All in favor of me grabbing a drift punch and seeing of they come out? It might be a pita because there is no taper in the cylinders correct?

Edit*  driving them out backwards will be next to impossible. There us not enough meat for a punch to grab with out risking damage.

They are blank firing inserts. Sometimes used in stage / prop guns. You should be able to remove them with no problem. They are only held in place by spring tension. To remove:
Insert a wooden or plastic dowel of a smaller diameter from the front of the cylinder.
Catch the front of the insert with the dowel
Tap out from front to rear
Clean any remaining powder residue from the chambers

You Sir are the man! Took all of 10 seconds to push then out with a brass cleaning rod! Slipped out easy as can be. When I was looking at them earlier today they seemed much more substantial for some reason. Thanks guys!

Pics of the inserts?

Also interested in seeing pics of the inserts, and congratulations on getting it figured out.  You might send AIM an e-mail since they may have sold more than one set up that way and they can direct other customers to this thread.

Cool deal, glad you got it figured out. I have never seen or heard of blank firing inserts.

No Problem. I'm glad that I could help.
A long time ago I spent a few summers working a prop master at a summers stock theater. This is only the second set I've heard on 'in the wild". My LGS acquired a large number of guns from a LE auction a few months ago. One of them was a mint Colt Trooper 6" nickel. It had the inserts in it and the walnut grips had been painted a nasty bright blue.

In case anybody cares at this point those are actually chamber inserts for use with .38 simunition rounds.  It is to prevent the loading of any live ammunition into the revolver during use of simunition rounds.  I have used these 1000's of times and there is 100% no doubt in my mind thats what these are.  Most departments kept a few of their revolvers after we transitioned to autos to let bad guys use as simunition firing guns because the dedicated sim Glocks are damn expensive.  Looks like you got one of them that had been used for simunition. I bet it had spots of red and blue in lots of places on it too didn't it?  TJR

No color spots. But there was stringy plasticy stuff I pulled out of the barrel rifling, and lots of sand. Thanks for the info, I guess my first guess on simunitions was indeed correct.

Wow, that's really interesting to see.

I popped over here because I ordered a Police surplus model 10 from Bud's yesterday. I always liked the heavy barrel 4" model 10. I'd like to get a few of them... eventually.

Model 10 was my first competition gun Then I upgraded to the race version heavy barrel model 10.


Now I shoot a STI so I dont have to reload often
