This should be of particular interest to Fuff, Jim Keenan, who know and understand...and to Jungle...who doesn't believe.
Recently I had occasion to address a return to battery problem on two pistols, owned by two different guys. One Loaded Springfield and one Colt Gunsite model. Both very nice guns, in fit and finish.
Both guns had slight spec issues, and I didn't want to get too invasive, since both were under warranty. One, I was able to get to run perfectly, with a slight hitch during a slidelock reload on the top round, and only if the slidestop was used to send the gun to battery. Slingshot provided reliable function.
The Springfield gave a hard "Ca-Chunk" on the go-to-battery until the third round was gone from the magazine.
Both owners were using the "best" 8-round magazines. One was made a little better by substituting proprietary 7-round followers and Wolff 8-round extra-power springs...but the top round still shoved the bullet back into the case...and sometimes would fail to go to battery on the top round. Other problems with the frame that aren't related to the functional problem kept me in the "Hands-Off" position until it was resolved by Springfield.
Interestingly, I produced a couple of the old, tapered-lip, late/gradual release USGI magazines...circa about 1940 or so...and tried them in the guns.
What a shock to hear the light "ka-chunk" in the Colt turn into a smooth
"Schlap!" as it went to battery on all rounds...and the Springfield's hard KA-CHUNK!" turned into a light one...with no more bullet setback and no failures to go to battery. And they worked the same way with hollowpoints and lead SWC ammo...
Both guys asked if they could buy the magazines. I declined. The really good ones are gettin' scarce.
Goodness gracious...What are we to make of this?
