Ruger MKI,II,III "Blast shields" tighten them up ....

[Jeepers]

a friendly reminder that "blast shields" are awesome for not only helping keep the internals clean , but will tighten up the frame/receiver fit

just sucked down a Pepsi and redid mine getting ready to go shooting my ole MKII, easy to make and will make a huge difference in a loose old gun
