It appears the barrel peen issue is abating. I have a new gun and the peen is only about 2mm unlike earlier models. Look for the recent post here and you’ll see photos. Peening doesn’t appear to be much of a problem any more but YMMV.The best option may be the base model with the factory metal 3 dot sights and upgrade later.
After reading several forum posts it seems a bigger issue may be the barrel peening. I may need to move up to a PPQ SC.
Thanks for all the feedback.
'Good to know. I would prefer sticking with the PPS. Thanks.My PPS M2 has around 1200 rounds through it with zero peening. I think the peening issue is very small compared to the total number of PPS M2s sold. Even some who report the peening issue, say it is very small and that it doesn't get worse after a point.
