Disaster at the range with my SP-01

[CzDave]

I have seen A LOT of WWB doing this to multiple guns lately. I think they had some bad batches. More than usual.

Did you clean and oil the gun prior to the first outing. If I read correctly this was your trial run. I have shot THOUSANDS of rounds of wwb. Its readily available, pretty cheap and works 99.9 % of the time over many years. Its my go to range ammo unless I get a deal on something else.

I have only had a gun lock up on me one time in many years and I have owned more than a few handguns.. It was a Springfield stainless Trp I bought new. It was just set up so tight that once the parts heated up it locked up solid. I couldnt budge the slide. It was the first time out and I too was bummed.

I let it cool and I was able to free it. I cleaned it and then racked it by hand in front of the tv about 500 times. Took it apart, oiled it and it never happened again and that gun was an insane tack driver. Most accurate gun i ever owned.

My suggestion would be the same. If its new clean it then work the slide manually a bunch. Disassemble. Oil her up and give it another go. Remember its a full metal on metal slide to frame mate. Inherently more accurate than a slide running in some tabs in the frame but a lot more friction.

When your done racking and you go to assemble make it a little more sloppy than your used to. If your experience is only with poly guns metal on metal can use a touch more oil in my experience.

should i change the recoil spring to a lower 13-15LB until it is broken in?

Thanks for all your input.

It...was...the....ammo.

Im gonna concur with this and Boriquas addition along with it.

Thanks for the advice, i did lube it before going to the range but when i came back i took it appart and oiled again. i will rack it as you suggust, and use a different ammo next time at the range, hopefully it was a fluke,

Someone had this happen with their Glock except a live round was chambered. Round fired trying to get the slide to reset, luckily into the ground. Most likely too long OAL.

I've fire many thousand of rounds of WWB and it always worked fine for me but that cheap Mexican Aguila brand stuff - no way.  The Aguila stuff jams often in my black 75B but the stainless 75B and my compact eat it just fine.  I think some dimension of that brand is out of spec but all three of my 75's eat WWB and anything else I feed them but the Aguila.  I found that the Fiocchi brand 115 gr FMJ stuff is very light recoiling in all my 9mm handguns and it functions great.  It must use a light powder load.  I love that brand for target shooting because of that light recoil.  But don't try it in an MP-5 on full auto.  It won't reliably cycle the action.
