Had my shield at the range today. Have a hard time loading the last couple rounds in both magazines. No trouble loading for 1911's in 45 or a Sig P239 in 9mm. Springs are just a little overpowered I think. Temped to cut a little off if I could find replacements in case I ruined them.
I hadn't ever used an uplula due to price but I got finaly one last week and put my shield through a good workout today. It is a great tool and yes, those shield mags would be a bugger on your hands without one.
