Another recent Wasp owner here with dead battery syndrome. Got mine late December 2021. Battery dead late Jan 2022. At Springfield now waiting on a replacement. Thinking I likely made a mistake here and bought a piece of junk. In addition to the battery issue, the windage adjustment screw on mine was crazy loose. I think I could have blown on it and it would have moved. I only had an opportunity to put 100 rounds through it after zero, and amazingly enough it held, but I think long term it was going to be a problem.
The Hex Wasp has some very similar design features to the Vector which is a really cheap piece of Chinese crap. My guess is the same company makes both the Vector and the Wasp. Springfield probably just had a few cosmetic changes (forward leaning hood, serrations), but the guts are likely the same. What I really wanted was the 507K, but do not want a plate, and do not want to modify my slide. For the life of me I cannot understand why Holosun chose to not make these fit the Hellcat without mods.
I don't have any confidence here that Springfield has fixed the Wasp issues. No evidence to support it, but just what my gut tells me.
Also see someone in another post saying the Trijicon RMRcc will fit the Hellcat. It will not without machining your slide or using a plate. It is significantly longer that others using the RMSc footprint.
