So I bought one of these. It did not like surplus ammo at all. Never tried the s&b though. And it had a habit of holding back the slide with one round still left in the mag.
To fix these issue were pretty straight forward. I ordered in a new wolf recoil spring for a sig 226. #15 worked like a charm. Now it eats any and all I put in the mag. Not expensive either.
And I had to file down the spot where the slide catch gets pushed on by the mag follower. Only a tiny bit of material had to be removed. No more stopping before the mag is empty.
Just a couple easy fixes if anyone else is having my issues.

Good to know, Thanks.

Who sells the Wolf recoil springs?
 
I bought mine from a big company in the states. I don't know who sells them in canada but if you Google it you'll find somewhere I'm sure. It's a pain to order anything out of the states these days.

Mine is leaving the last round in the mag as well...I sent a message to Canam and was told to try leaving them loaded for a week or two to try and break them in. If that doesnt work I was told we would go to plan B .
Could you show a pic of the modification you did to the slide catch and thats good news about the recoil spring as I have 1400 rounds of czech surplus that my gun hates ..lol
And they are double stack magazines jcoulson .
 
Ok so I've never written a guide or posted pics on here before but i think i have it sorted out. If I'm not clear let me know.

This is the spot i had to file down.

To do so easily i removed the front block and flipped it up

I also bent the catch spring a little bit to push down harder onto the catch... (sorry i forgot to mention this before, but its really easy to do.)

To gauge how much had to be removed i inserted a mag with 1 round into the frame without the slide. when i pushed the mag into the well hard i noticed that the catch pushed past the groove the slide rides in. So with 1 round in the mag, it definitely caught the slide... I had to remove a little material from the spot in the above pics using a small flat file I bought. It didn't take much and it cleared the slide. Keep in mind it was important that i was pushing the mag with 1 cartridge into the pistol while i was checking this clearance. As i worked i kept checking it with an empty mag to make sure it was pushing plenty hard enough up to catch without any ammo.
I took my time... I was worried I'd end up screwing up my new gun or having to order a new part.

Now with one round in the mag and pushing it into the well, the catch clears the slide by a tiny bit, but it does still move a little. No more problems with it hanging onto the last round.

So my verdict.... With a little work my gun works flawlessly. Since putting in the new recoil spring and the other work to solve the 1 round left issue I've put about 1000 rounds down range without a bit of a problem. I think the problem is caused by a bit of sloppy tolerances in the manufacturing of this gun. I'm glad some peoples work well for them, but in my case it took me hours of work and reading to figure out what the problems were and how i thought best to fix them. Since I'm new to handguns I do actually appreciate the learning.

By the way... I'm not a gunsmith. You start filing on your gun, and screw something up, don't blame me. I'm just telling how i got mine to work right.
 
Good job and thanks for the pics and info on how to do this.....I will do the same mods to mine and post how it went .

Well I just figured out that the pistol has to be decocked to get the block out and if you bend the catch spring too much the slide wont stay to the rear with an empty mag ..lol . I bent it back a bit and it seems fine now. I am waiting for my recoil spring kit from Brownells to complete the mods you did.

Is it suggested that replacing the Recoil Spring allows for a harder strike on the primers allowing for more reliable use of the Czech surplus? I would have thought that only a stronger Hammer Spring would do that.
 
That is what the OP did... he put in a #15 . I ordered the Wolf recoil spring calibration kit from Brownells 969-000-205WB .
It comes with a 15,16,18 and a 20 lb recoil springs and 3 other extra firing pin springs in the kit . With my discount is was $16.66 US

But did he ever specifically state that the problem that was resolved was the need for extra firing pin strikes on the hard primered Czech surplus? The only resolved problem that was described in any way, had to do with feeding from the mag.

OP?
 
OP is other person .. legions_flag and he said that he has fired about 1000 rounds now of surplus ammo with no issues.
 
The recoil spring has nothing to do with the strength of sticking the primers. The issue I was having was that the gun wouldn't chamber cartridges reliably. Usually had to bump the back of the slide to get it to go into battery. If your gun isn't striking the primers hard enough the ignite I'd look into a hammer spring kit. I have no idea if a kit designed for a p226 would fit.

And chalk, I'm not sure if it would be a good idea to put in the new firing pin springs that kit comes with. I'm thinking the stronger springs may cause lighter primer strikes. Besides there is a firing pin block in this gun that should prevent it from slam firing from a too strong recoil spring. If you do decide to change it out let us know how it goes. And my advice is to look up a disassembly video for the slide before you try it..... mine was 17 kinds of hell to get apart.
 
All I was planning on using was the #15 spring as that was the only way I could get one was to buy the whole kit. I read your post and assumed it was the light primer strike issue that you were having with your surplus ammo like I am . Go figure someone assuming something and making bad decisions or statements on CGN ...lol
Oh well the kit was only a few bucks and I got to learn how to disassemble some more of my pistol in the process.
I think that other work may have cured the mag issue and will take it to the range in a week or two.

Thanks again
