Please keep us up to date as you do more shooting. I really appreciate you coming back to let us in on how it went. I was thinking about doing an Alaskan like this or the 625MG like what you have. I still may send it off to them.
 
Re: "LC is for Long Colt = Revolvers / apc = .45 auto / keep it that way"

I don't know about conversions, but 625s produced for .45 ACP are highly popular among competitors.
 
IMO that pic of the slightly engraved, non-fluted cylinder made a handsome gun even nicer to look at. And .45 acp or .45 LC is plenty of gun for most uses.

but that's just me....
 
Here is a woods stomping pair... sure, my 625JM can reload faster with moonclipped ACPs - and I have loaded ARs a tad warmer than .45 Colt. There is just something neat about the first revolver round I tried - the .45 Colt - and this, my first-ever S&W - a 625MG in .45 Colt. I really like the 'traditional' shortened lug, chafered cylinder, and tapered barrel. I liked it so much I bought a '96 version just like it. The Buck Kalinga Pro (#408), with an S30V blade, is new this fall.

PS Just what kind of cost is invlolved in the ACP conversion... how can I get in touch with Pinnacle... ?

I know, I said I wouldn't... but...
 
i had a ruger 454 alaskan cut for clips and it will shoot acps with clips and 45colt and 454s with or without clips.(obviously differnt clips) acps feel like 22s in it but the between the fact that the point of aim is about 8 inchs off and accuracy is pretty dismal it would be about good only for a survival type use.
 
Range trip #2

I cleaned the gun thoroghly and took it back to the range today. I must have been having a bad day Monday (like time at the range could actually be bad), because today, it shot great! 12 shot groups fired off hand and double action at 15 yards under 2" consistantly. Whew! I feel better now. This one is definitely a keeper. :D

Tex, what did it cost? Did you send the orignial cly or replacement? Does it need special moon clips? And are there compII or III type speed loaders for this gun in 45LC? My wheels are spinning a hundred miles an hour!
Thanks, Lenny
 
Lenny,

I sent the original cylinder along with a check for $87 which included return shipping. It uses standard full moon clips. To my knowledge the only speedloaders for the 45LC in this gun are the HKS 25 or 25M. No comp II or III.
 
Have you ever weighed it? I'm think IDPA SSR (if less than 42oz) and ESR. I know it may not be the MOST competitive set-up but fun is fun. $87 sounds like a bargain to me!
 
I was under the impression that .45acp used .452 bullets and .45LC used .454? Is this correct and could it be causing slightly less accurace with the .45acp loads?
 
Brasso, I believe .454 was the "old" standard diameter for the Colt. Somewhere along the lines they went to .451, .452. Someone more knowledgable could shed some light.
 
The 625MG in .45 Colt uses the HKS #25-5 speedloader for .45 Colt, while the straight HKS #25 speedloaders have the wide-spaced tines needed for the .45 Auto Rims' thick rims. It will actually hold the .45 Colts - but they are loose. I also used the HKS #25-5 with my .454 SRH and .45 RH - with .45 Colts.

Prior to WWII standard 45 Colt groove diameter was .454. In 1956, 45 Colt groove diameter was changed to .451 to match 45 ACP groove diameter.
 
For .45 Colt, I use the S/L Variant "jet-loaders" made in Germany. There is a spring behind each cartridge that throws it into the chamber. The size is based on the diameter of the case, not the rim, so this model works with both .45 Colt and Auto Rim. No rattling, since they are under spring tension.

Anybody know, Is there any reason you could not shoot .45 win mag through this newly converted cylinder and still retain the use of full moon clips? I just realized 1/2 or 1/3 clips would not work due to the outside lip holding the Colt rims.
I cannot find OAL of .45 win mag cases.
 
Question for today is If I have a 25 or 625 which gas been modified to shoot both .45 ACP and ,45 LC, can I safely shoot .45 Win Mag in it. Or will this cartridge bend my frame? lol
 
I am pulling this one out of the grave yard and want to know about the 45 gap load, could you put it in the acp moonclips and shoot it? I am not looking at this as a primary load for the gun but just as a gee wiz as another round that this gun could shoot. I am looking to have this conversion done to my 45lc mountain gun. HighVelocity how is your accuracy now? I know its been a while but is it still good in your gun. Have you had good range days with this gun?

Thanks,
 
If you do have pinnacle mill a .45 colt for taking .45 acp clips, is there ANY drawback whatsoever? Is there any additional risk of light primer strike on .45 colt?
 
KurtC, what model is that? Beautiful gun. And what grips?

For those with black 625s, what finish was applied to make the stainless steel black? Aren't all 625s by designation, stainless steel models?

If I have a .41mag and a .45LC do I really have a need for a .44mag or .44spl?
