Took my 108284 and put another 100 rounds through it this weekend. At the end I tried to release the slide and it wouldn't go forward on the empty mag. Using Wilson Combat mags, had no malfunctions at all with my reloads. So I dropped the mag, and was able to release the slide. Tried inserting the mag, and rack the slide, still tried a huge amount of force and the slide would not release. After several attempts I did manage to get the slide to release on the empty mag, but only with excess force. Can't imagine the gun was excessively dirty from only 100 rounds, as it had been cleaned before the range session, and oiled and slide greased. Any thoughts, suggestions would be appreciated. Thanks in advance.
