After switching the top-end of my Open Gun to 9mm Major, one of the problems I’ve been having is magazines. I only have three 170mm magazines and one of them is a SPS version which although reliable with 38 super, is not with 9mm major because of the overall length (OAL) and the rim in the case. The most reliable magazines are the STI and SV magazines. With the STI, you need an additional “spacer” to make the magazines work with 9mm Major. For SV, you don’t need to because of the construction of the magazine tube.
I chose to go with all SVs so I don’t have to mess with adding spacers. I found a seller online who still had the old style SV magazine tubes and got them for $150. yes, $150 just for the tube!!
Nice and shiny.
The best combination for maximum number of rounds is the SV tube, Grams 13 coil spring + Follower and the Bolens 3mm basepad. Ordered those parts from Shooters Connection for another $60.
$210 for ONE magazine. Yes, shooting USPSA Open Division is bloody expensive!!!
Spent a few hours today working on my 625 JM and tuning up the trigger. I bought the Jerry Miculek S&W Revolver Spring Kit that he sells off his website Bang, Inc. and decided to follow some of his instructions on the Trigger Job DVD to smoothen the trigger action and associated parts.
I know this sounds dangerous and amateurish, yes indeed it is but what better way to learn about the gun than to try it yourself? If I screw up, then I’ll send the gun to Carmoney or Jerry to get it fixed. Consider it an educational fee
Here’s my original Trigger pull weight :
Here are all the pieces that I worked on :
and after fixing the action, polishing the internals and reducing the mainspring weight :
the action is much smoother, but I am still very skeptical. It feels like the firing pin will not be able to strike the primer properly. I have loaded all my revolver rounds with Federal Primers and seated each one very well but I still do need to test this out on the range, best way to find out.
What’s good is if it doesn’t work, I’ll just tighten the strain screw a little bit and test it again.
*UPDATE* Here is the 3 part series of my gunsmithing adventure!
