I purchased 2K of Servisios and Adventuras primer made in Argentina several months ago. Price was about what everyone is paying. I have been using the primers exclusively to work up loads and also to test them for reliability. I have had mixed success with them. I usually get 5 out of twenty that will not fire without multiple hammer strikes or rotating the cartridge in the chamber and then having them work. Background, these are being tested in a Beretta M9A4 with an MCarbo trigger kit installed. Various projectiles both clad and lead are being used and mixed brass for testing. The primers seat easily with my Franklin Arsenal perfect primer seater. It has a great adjustable seater aspect that requires a thumbturn wheel be turn 1 click up or down to get .001 difference. I have used the full extent of the adjustability to the point that the primer ram is making a small circle on the primer when I have gone too far. I usually seat just below flush. I didn't feel that made much difference. Maybe its just my combination of parts and pieces that are creating this condition. Winchester and CCI primers just work every time. The SA primers are just not consistent but the saving grace for me is that while I won't use them for when it counts, I will continue to use them for the advantages of training for sight picture follow through and double action practice with the Beretta. My double action technique has improved significantly. So, there is a silver lining after all. Maybe my experience will help someone else.
 
My experience with these primers mirrors yours. 10-12% failures was a good outing. My Beretta 92 was close to 50% failure with different hammer springs. My revolvers gave me about a 15% failure rate. I still have 1000 of them left to load. I agree about improving my trigger pull. Not knowing if it will fire or not has been great practice.
 
I bought 4k of the S&A SPP and shot a few hundred without any failures. These were shot in S&W Model 10, Ruger GP100 and Ruger Service Six with stock springs. I've loaded 600 158gr Xtreme RNFP over 4.3 grains HP-38 using S&A spp recently and will test them over the next few range trips and report.

My experience with the S/A primers has been 100% reliability in double action revolvers (S&W Model 28 and a pair of Ruger GP-100’s) for several hundred rounds. Striker fired Glocks haven’t been as reliable. I am still experimenting, really cleaning and uniforming primer pockets and extra effort seating primers seems to improve performance. Also hammer fired CZ’s seem more reliable than striker fired (P-09 and SP-01). I figure I can use the S/A in revolvers and save my CCI-500, Federal 100, and Fiocchi for the Glocks.
