I have both. It is true that the MP1 MRO handles aren't as grippy as the MP1. The MRO feels more plasticky. However I wouldn't let that dissuade you overly much. If it is of much concern to you, I would look at a Series 3 Multitasker instead.
I hate to break this to you but the Gerber MRO is a shooting oriented tool.check out my episode 41 entry in this thread (page 3)...http://forum.multitool.org/index.php/topic,65364.0.htmlThis is why I mentioned the Multitasker. Both are tools to help maintain an AR type rifles. Like you said however, there are many other uses for the special tools found in these that make them useful to folks that do not have or need weapon specific maintenance tools. EDIT: Sorry, I was thinking about the MP1 AR tool...The MRO is a different tool...and one I do not have. However, it looks like the MP1 AR tool..so my original comment stands in regards to the feel of the handles. Looks like I will now need an MRO for the collection lol.
It definetly lacks the grip, but I dont find grip that important as I have never had tool slip from my hands anyway. Grip is overrated. Id say go for it if the toolset is important for you.
Basic MP1 has the best Gerber pliers ever. For me that is. The off centered cutters are really handy for cutting zip ties clean. There should be more of those around.I'd say that many Leatherman pliers feel a bit more robust still but it depends from your line of use. And my MP1 has taken abuse, where my Waves and Charges have failed.The plier size is close to SOG PowerPlay and Wave too.
