I am looking to purchase the FN .45acp Tac handgun..... FDE color. When I initially started looking into these handguns I was quite certain the gun I wanted was listed as: FN FNP .45acp Tac. The other day I was looking at this same gun (what I thought was the same gun) but noticed the gun was listed as a "FNX".....not the "FNP". I know this is very likely a stupid question but can someone tell me what the deal is here? I read somewhere that the FN FNX .45acp Tac is simply the updated version of the FN FNP .45 acp Tac, is this true? I just want to be sure I purchase the correct FN .45 Tac model and am a little confused right now. Does FN make both of these models each year...the FNX and FNP? Anyway, I will really appreciate some help with this for those who are in the know........ and will happily apologize beforehand for being a dork about this. Thank you.
