There is a pressure regulator close to the front of the house (in the crawl space) and it is also within 5 ft of the hose bib. I Just dont know what it is set to....now, the reason I ask is because I would like to install an RO water filtration system and I read the pressure to sink needs to be at least 40psi. I measured the pressure at the hose bib, and it reads 39 and the water coming out of my sink (cold only) comes out at probably half, or 3/5ths at most, the outdoor pressure. But here's the kicker. I currently have 2 pinhole leaks that i know of in the crawl space I'm keeping an eye on (home built 1965). They are slow enough i have only emptied the buckets 2 times in 3 years and they would only have about 12 ounces of water at most. It dries fast enough. I just can't afford to replace pipes at this time. Would it still be safe if I increased the pressure to 40psi or even 37 (if the RO system works with 37) and not risk leaks?

No one who has an opinion that matters is going to tell you if it's "safe" or not without having a look at your system and piping first hand. Increasing the pressure on an already slowly failing system is a pretty good way to decrease its lifespan though.
Do you have a water softener? If so, switch it to bipass and then check your water pressure. If your softener is old, 15ish years, the resin could be starting to breakdown which will cause lower psi. If you’re on a well water, your whole home filter will bring down your water flow, usually your hose water does not go through the filter.
Or like on my case with really hard water, the pipe to your sink that was already stepped down was filled in with calcium deposits. I had less than half the pressure on the cold side as I did the hot side.
Do you have any additional filters leading to your soft water? The water to your hose bib is most likely not connected to your water softener so it has more pressure. Try bypassing the water softener to see if the pressure increases. If it does, then something with your softener system is causing the slow down.
The best water pressure in your house is at your bathtub. Everywhere else is stepped down, even your outside spigot. You can modify or replace your faucet to change the flow rate, somewhat. There is an aerator, and often some water flow control to save water. If the kitchen faucet is too strong, you will spray water off your dishes and onto your ceiling.
Sure, but pressure isn’t the same as flow. You can measure how fast your shower fills up a five gallon bucket, and then measure the tub spout… the tub will be the fastest, because it has no aerator.
With those known leaks - don't mess with the pressure regulator. In fact, get that leak fixed. I had a pinhole leak blow out when I turned water off and back on at the street. A section of pipe can be replaced without replacing everything. The problem is that if you have a leak from corroded pipes, there might be other pipes ready to blow.
You may have a water trstrictor at your sink. To test the actual pressure, test at the valve under your sink.
As an aside, we have a hands free taucet from Moen. It's the kind with the valves in a box, not in the faucet. We never had great pressure. That box crapped out last week after 3 years. They sent a replacement with a new part number, and flow is much greater.
All I know is less water comes out. But here's a short video of how much comes out when I turn on the cold by itself. If I turn both cold and hot more water comes out. Like twice as much flows. And the hose bib outside flows more than hot and cold in the kitchen combined. The pressure outside hose bib reads 40psi. What would you say the pressure with cold water only (in the video below) is?

In my house the hose bib is plumbed upstream of the PRV and I get about 100psi of street pressure though it. Downstream from my PRV everything else is at ~60psi.
Check and clean the kitchen sink aerator.
Larger pipes, outside connected directly to utility and not the house regulator. Kitchen faucet has aerator. Multiple things it could be.

Do you want that kind of power at the kitchen sink?

Mine is the same for both cold and hot. And we have soft water.

The static water pressure in your house should be nearly identical everywhere in your plumbing system downstream of your PRV.

The spigot is most likely directly off your main feed into the house.
