I will no longer shoot steel in my handguns. I have had or personally seen 3 critical failures with steel in about 15yrs.
1. The first was a glock 23 with wolf polymer coated. fired casing stuck in the chamber, would not come out. had to take the gun apart and pound the casing out with a dowel rod. My friends gun, were were out on private property shooting.
2. at a range. HK pistol, I don't know what model, wolf polymer again. same problem, fired casting stuck in the chamber, would not come out. he packed up and left.
3. My G19 with red army. first round bang. 2nd round click, primer was well dented but a light strike. fired the 2nd try. round 3 bang. round 4 pop. the gun was locked up. it was a squib gun locked up. managed to get it open jamming the slide on a table. bullet was in the casing, primer was blown half way out the back.
The issues with steel as I understand it.
Steel is harder and can wear your gun faster
steel is stiffer, and does not expand to seal the chamber as quickly or as well meaning you chamber will get dirtier faster
steel usually has a coating to keep it from rusting. usually polymer, sometimes laquer. in time and with inadequate cleaning they can build up in the chamber and cause malfunctions or just be hard to clean.
steel can and does work. many people report having good luck with it. Me, personally, I will never put steel cased in one of my handguns ever again.
If you want to try it out, just buy a box or 2, not a case. put it through your guns, see how they run with it.
