hello, i recently purchased a mossberg 535 second hand as a first gun. would like some feed back from other people that use the same gun, problems that they have and what they like about it. im having a couple of problems with the one i purchased, the mag tube is only taking 4, it will fit 5 but jams the spring up at the top of the mag tube, will a mossberg 500 spring work as a replacement? also having problems with the forend, i had the pins that hold it on fall out, took it to a shop and they did an alright repair by glass bedding the forend to the rails with small screws where the pins were. if i were to use a mossberg 500 forend how much modification would i have to do? i know i wouldnt really be able to just use the 500 rails without a good amount of grinding. any and all help would be much appreciated, cant really seam to find any info on this gun on the web, or parts for that matter.
