Can't speak for Beretta but stock Sig mags (Blue, made in Germany) are terrible and it's likely not the magloader at fault. They are gritty and will only hold about 9 and a half rounds. You need to order some nice Mec-Gar stainless direct from Mec-Gar in the US. They will ship promptly and at $30 a mag you can slide 10 rounds in all day long with no trouble. Beats spending $40 to $60 for mags you can only fit 9 rounds into. I bought 10 and never looked back.i have one and use it with my beretta cx4 and my sig p226, it can only put 9 in eachapparently thats a fairly common prob. you are lucky
