If your NOT a reloader then I have issues with 10mm in the current spec of factory loadings....it got lawyered (and I date a lawyer so I understand the issues here..LOL) down to a mere shadow of its original self...the original 10mm spec loads from Norma were HOT...200gr loads leaving the muzzle at nearly 1300fps...WOW...that gave you at 100 yards the same or more energy that a 45acp 230gr ball load had at the muzzle...the Bren 10 being a upsized copy of the CZ75 meant it had the strentgh handle what ever you could stuff in it and most likely more...other 10mm's...not so much.....so SAAMI (hope I got the acronym right there) emasculated the 10mm till its not but slightly better than the 40 Short and Whimpy...but if your a reloader and understand the limits of your gun..then rock on brother..the 10mm is fantastic.....just make sure your gun is capable of handling any loads above current SAAMI spec
