I have had a model 383 for many years. it's been a good gun and I carry it a lot. I have developed a problem the rounds getting stuck in the magazine and not feeding. I can only load 2 or3 rounds before they become very tight in the clip. I have cleaned and checked the mag and do not find any obstruction. the plunger it's self seems to be free and travels smoothly up and down. I have tried 3 different types of rounds with the same result. anyone else had this problem?
