I popped few thousand (about 5000) of 3/16" and about 500-600 1/4" rivets. I killed 4 guns but they were replaced with no charge. The killers were 1/4" stainless rivets. You can't even compare 1/4" rivets to steel rivets, they are real PITA if you try to use hand tool.
If you use this kinda guns with aluminum or even steel rivets they work great and will last a few bus rebuilds.
I got the same gun. I never even unpacked it.
Getting the rivets was too much head ache where I live, and I didn't have the time to wait last fall. I was trying desperately to get the Four Season Prime livable before winter, but failed.
I'm also doing this entire project without the use of 120 volt electricity. Running a compressor means running a generator. I hate the noise, the cost of fuel, and the smell.
All the small bolts I used were installed with cordless Dewalt 20 volt max drills. It was quick and efficient. Batterys get charged while I'm driving, or at the job sites I work on.
Unlike rivets, The bolts could be installed and removed when needed, for mock up and placement of the steel sheets. I also used large #14 hex head self tapping screws for temporary placement.
I'm also not welding my hat channels together. Even though a 1/4 stainless steel rivet has around 500 pounds before sheer, fellow members were voicing concerns about strength. So I stepped up to 1/4 inch bolts.
Last was cost. The rivets would have ended up costing more per rivet.
