please elaborate on "improper cleaning". I assume you are talking about the usual fear everyone seems to have that an oiled striker WILL fail (even though mine was oiled and not cleaned for 1000+flawless rounds). I swear everyone here works for an oil company because you can never let someone bring up a "walmart oil" without mentioning that your personal lube is better. I have a lot of different products that I use on my gun and my bike. For my bike, I use dry lubes to minimize mess transferred to other parts but for my guns, anything goes. I've used just breakfree, just remoil, S&W CLP, and even just Hoppe's without any lube applied. the results? my gun is clean and working. that's the goal and I think I've met my goal. Not sure your oil is good enough? does it get your gun clean? does it work? There you go.
