you may try a modified uplula, such as for the cz kadet..
there are DIY instructions, or you can look for ones modified by den stinnett
on the cz forum, look in either the kadet section, or the sale forums..
its some of the best $$ I have spent on a accessory..
and worth the price..
pretty much loads most mags except the really slanted 22 type like a hi standard, colt woodsman, buck mark, or mk iii..
