Not sure if anyone has seen this mini review and I don't think it's been posted here before. I wish we were allowed to hack down the barrel and add a suppressor.

Hi, new cx4 owner here. . Just picked up a restricted one and will be sending to epps for heavy profile non restricted barrel. . Have a question , are the 5/30 or 10/30 rd 92s mags available in Canada? If so where and are they compatible or would I need to buy the magwell adapter?
Thanks!
Thanks!

pistol mags are allowed 10 rounds, so no need to limit them to 5.
mine takes 92/96 mags.

I owned a cx4 that had been made non restricted and Chambered in .357 SIG simply put it was the most used useful firearm I have ever owned for use around the farm , it was compact and light enough to be with me when many rifles were just a pain and got left , I fell in love with the CX4 and the .357 Sig round .
I hit coyotes with Iron sites at 75-80 yards given it often involved 2-4 rounds , that rifle became a extension of my body , I shot Skunks , coons and many Coyotes it is such a well designed little rifle for use from Snow machine or quad in .357 Sig its even useful for deer .
I wish I never sold that rifle , it had feeding issues with certain mags for the most part .40 Cal mags were 100% I had 2 that fed perfectly , I found the .357 sig way way more useful than 9mm .

Pm sent, thanks!
Typically, these items are PTS-equivalent to airsoft grade. I have a few on my tacticool rimfires and I have nothing bad to say about them. If and when they break, meh, you won't see me upset about it, though I fully understand these are not 'real'. I don't imagine you will be abusing the accessory too much so, for the savings, I won't criticize!

Dang, I didn't know you could do em in .357Sig. that's cool. do you have to change the bolt, spring etc? special mags or does it feed from Beretta mags?

thanks. I can't see it happening in the near future, but if I end up with a few extra bucks, I would like to try that. what about the bolt, springs etc? is it just a barrel swap or what all is involved?
Hi guys, I joined the Black gun club and bought a new CX4 in 9mm. I mounted a Vortex Sparc ii red dot. Love the gun with the exception of the heavy trigger pull. I purchased the Sierra Papa trigger/hammer/spring kit from A ####h armory. Sierra Papa noticed some variances in the tolerances of newly produced CX4s. They now include a sear clip in the kit but it is not always needed. South of the border, Sierra Papa installs the kit for you but here in Canada we don't have that option. I have not been able to get my hammer to #### properly with or without the sear clip.So far A ####h has refereed me to Sierra Papa, Sierra Papa said A ####h will be contacting me. So, I wait. I am looking for any links or suggestions on how to adjust the trigger travel set screw as this can affect hammer reset. Sierra Papa removed the link they had on their website. Your thoughts or suggestions appreciated. Thanks

I'll try my best. Not going to take it apart to take pictures, then upload them, then post them all, but I'll try my best 
if you can #### the hammer by hand once the trigger is installed into the housing, with the clip in place its good and you need it. often it may be a bit hard the first time or two. I made the mistake of thinking that I didn't need it as it cocked and held it nicely with out it and it was hard with it so I left it out.
It appeared to be just fine. it would #### and eject and fire every time by hand with dummy ammo. I then adjusted the trigger to where its supposed to be. How you do that is you adjust the screw in(tighten it) until the trigger will not reset. You will know as the hammer will #### but the trigger will not pull due to it not resetting. it will feel the same as before you cocked it again. Then you loosen it 2 turns or so.
However, when I went to the range, the thing would fire once and then no trigger reset. I backed the adjustment out half a turn at a time until it was not contacting the little bit on the trigger anymore and it still did this. Very annoying. I would get the occasional 2 shot setup. not a burst but two in a row that would shoot. It would ALWAYS shoot again after I re cocked the thing. However it would never shoot more than once except for the occasional two in a row.
I called Sierra Papa, and they were great, and phoned me back on their own dime to talk me thru it. I was at work, so I wasn't able to actually work on the rifle with them.
I kept playing around with it and I found what turned out to be the solution. If I cocked it and let it slam home(simulating a firing cycle) it wouldn't reset. However if I helped it close and not let it slam home, it would always reset the trigger and let it be fired. I did this a few times and it was fully repeatable. Turns out that when the bolt slammed home it would let the trigger go and the hammer would follow it. So its not cocked anymore. If you helped the cocking lever forward and not let it slam back, the hammer would not get tripped. Thus, a round would be chambered and the hammer and trigger were still cocked, ready to fire.
So I put the little clip back in. Hammer was tight, so I worked it a few times by hand and it loosened up a bit to be about right.
Reinstalled and reassembled the whole firearm. readjusted the trigger as per the original, and tested it by hand. Absolutely no problems at all. I could slam it forward with gusto and the trigger would still be set and the hammer would still be ready to go. yay! Tried it lots, no problems.
Off to the range. 10 rounds? No problem. another 10 and I got one no reset, so I backed out the screw half a turn. 150 more rounds and no problems at all now.
Trigger is great, little carbine is as it should be. I suspect that with the little steel clip in place and interfacing with the steel part on the trigger sear, it will last longer as the original plastic won't wear out as quickly. It feels nicer too. Crisper break.
oh, one more thing. This trigger works by pulling the trigger group housing against the lower receiver. In the stock setup, there is slop fore and aft between the housing and receiver. I shimmed the front of the housing with card stock. You will need to cut two pieces, one for each side of the front of the housing. I forget what it is, but there is something in the middle of the housing that prevents you from using one piece. Don't worry tho, its easy, just measure and cut. Then hold the housing rearward and slide the little pieces of card stock into place. its a decently tight fit. mine fit nicely with a business card. The housing does not move at all now. Quite a bit less slop in the trigger now, and its even better than just the trigger parts from Sierra Papa.
I suppose one could do it with nicer metal parts, but its been several months now, and there are no problems with the card ones.

Thank you JR for your response. My experience is similar to yours. Without the sear clip the hammer would fall from the jar of the bolt moving forward when I used the slide release.
With the sear clip in place the hammer is difficult to #### and I can't get more than 1 shot at a time. I will try as you suggest and leave sear clip in place and loosen the trigger set screw. i too would like to be able to leave the sear clip in place. I had the safety pin upside down once and that didn't help. I'll keep tinkering with it.
Thanks

Just got back from first day with my new (used) CX4. WOW! What a hoot that was! Got the RDS sighted and just had a blast punching holes. This one will be out to the range often. So glad I bought this one. Great deal on a non restricted on the EE right now too. Doh!
I'll join the thread now. I have been back and forth on which gun to buy in this style. I checked out the JR, looked on EE but I wanted th Beretta all along so that's what I went with. I put a cheap NC star on it to start but I have to look through the rear sight to see the dot so that's got to go. I'm thinking a reflex sight but I'll decide that soon. I put 93 rounds through on the day I bought it, shoots as fast as I can pull the trigger. Very fun gun in a cool round, 9mm is new to me.

JR Carbines are crap. A local store refuses to carry them because they have so many issues.
